Duplicate PTA

I'd like to use the Duplicate PTA option, but it's not enabled. 
 What Duplicate PTA does: Creates a full copy of a past event, including the same class and enrollment data — but not time slots. This is intended only for events with unchanged enrollment , such as full-year classes. Since using it incorrectly could overwrite intended changes, we enable it selectively rather than by default. 
 
 If you plan to import new data files: 
 You don't need Duplicate PTA — instead, create a new event using a previous event as a template , which copies over your previous settings (without enrollment data): 
 
 Go to Events / Preview. 
 Click Add . 
 In the Template Event drop-down, select your previous event. 
 Click Add . 
 
 
 If your new event will use the exact same enrollment data as the previous one: 
 Let us know, and we'll enable Duplicate PTA for your account.
